Principal value of arg(z1z2) may not be equal to Principal value of arg‌z1+ Principal value of
Lt
2
Principal value of arg(z1z2)= Principal value of arg‌z1+ Principal value of arg‌z2
Principal value of arg(z1∕z2)= Principal value of arg‌z1− Principal value of arg‌z2
Principal value of arg(z1∕z2) may not be arg‌z1−arg‌z2
